Hacker known as "Pinkie Pie" produced the first Chrome vulnerability at the Hack In the Box conference on Wednesday, just ahead of the deadline for the competition this afternoon.

The exploit, if later confirmed by Google’s US headquarters, will have earned the teenage hacker known as Pinkie Pie the top US$60,000 cash reward.

In March, Pinkie Pie and Sergey Glazunov both won $60,000 for their exploits at the first Pwnium competition. Google established the Pwnium competition as an alternative to the Pwn2own contest in order to add the requirement that participants provide details of their exploit.

$20,000 - “Consolation reward, Flash / Windows / other”: Chrome / Win7 local OS user account persistence that does not use bugs in Chrome. For example, bugs in one or more of Flash, Windows or a driver. These exploits are not specific to Chrome and will be a threat to users of any web browser.
